On the stimulus duty cycle in steady state visual evoked potential [PDF]
, 2014 Brain-computer interfaces (BCI) are useful devices that allow direct control of external devices using thoughts, i.e. brain's electrical activity. There are several BCI paradigms, of which steady state visual evoked potential (SSVEP) is the most commonly

Visual evoked potential estimation by eigendecomposition [PDF]
, 1998 In this paper an eigendecomposition method is presented to estimate evoked potentials (EP). Taking into account of the characteristic of evoked potentials, the method uses two observations both of which contain desired EP signal and undesired EEG signal.

Top-down effects on early visual processing in humans: a predictive coding framework [PDF]
, 2011 An increasing number of human electroencephalography (EEG) studies examining the earliest component of the visual evoked potential, the so-called C1, have cast doubts on the previously prevalent notion that this component is impermeable to top-down ...
